Filtres de traitement des liquides

Les filtres pour processus liquides sont utilisés pour séparer les particules et les fluides dans une suspension. Lors du choix d’un filtre, il est essentiel de sélectionner le bon type pour répondre aux besoins et exigences du système. Les filtres se déclinent en trois grandes catégories : filtres à cartouche, filtres nettoyables en place (CIP) et filtres à sac. Une grande surface filtrante dans certains modèles permet d’éviter la cavitation de la pompe, tandis que les versions en acier inoxydable ou en polymère offrent une compatibilité chimique.
